ABSTRACT:
A shoe having ventilating means for supplying fresh air to the interior of the shoe has a base sole and an inner bottom sole defining between them an air distributing chamber and a space for accommodating an air supplying chamber to the rear of the air distributing chamber. The inner sole has an aperture therein between the air distributing chamber and the interior of the shoe for passing air from the air distributing chamber to the interior of the shoe. A collapsible resilient air supplying chamber is provided in the space for accommodating the air supplying chamber and having an air distributing conduit extending therefrom into the air distributing chamber and having an air intake conduit extending thereinto from outside of the shoe. Counterflow preventing valve means are provided in each conduit, and a rigid press member has a forward end anchored in one of the soles and has the rear end extending into the space for accommodating the air supplying chamber above the air supplying chamber. When a wearer in walking in the shoe raises the rear part of the shoe, the air supplying chamber is pressed against the press member for pumping the air supplying chamber into the air distributing chamber and thence into the interior of the shoe, and when the rear part of the shoe is lowered and the air supplying chamber regains its initial shape, fresh air is induced into the air supplying chamber through the air intake conduit.
